I'm posting here because although I've done extensive Googling, checked manufacturers' websites, and so on, I still don't feel that I have an adequate answer of whether it's safe to use my cup again after using it while having a yeast infection. Does silicone harbor yeast? Do I need to wash my cup a certain way? Is there no hope, should I just throw it away and get a new one?

Some background under the cut...

I had an untreated yeast infection for ~11 months (yikes, I know, but it kept coming and going, and was pretty mild, so I didn't really know what it was; thought I was having an allergic reaction or something). Was using my Lunette cup every period during this time. Finally went to the doc, swab test was positive for a YI, took Diflucan and was wonderfully relieved. Had some vulvar irritation right after my next period (during which I used my cup without issue) that cleared up on its own. Fast fwd to this period - I start getting itchy again right before it's due to start, but assume it's nothing (I'm pretty bad about that apprently). Couple days later I'm sure it's another infection, so now I'm using OTC treatment as the doctor recommended if it came back. But I'm concerned about using my cup next time - since I used it between taking the Diflucan and getting another YI, did I reinfect myself? I usually just very thoroughly rinse my cup with cold water when I empty it, and "sun" it to eliminate any odor. I'm struggling with what else, if anything, I should do to clean it without compromising the silicone or introducing an irritant to my vagina if I use my cup again after cleaning it.

I inquired with Lunette years ago about this when I used to get yeast and BV quite frequently. They told me to boil the cup for 20 min. Hint: Put in inside an all-metal whisk to keep it from touching the bottom of the pot!

Also keep in mind the bags you store your cup in, could harbor yeast spores. If they are 100% cotton, you can boil them also. If they are made of something else, you may be out of luck. I used to soak my satin lunette bags in apple cider vinegar and then wash them thoroughly with Lunette cup wash, but it took forever to get the vinegar smell out.
